A two-week field operation was conducted in the John Day Reservoir on the Columbia River to image the floor of the pool, to measure the distribution and thickness of post-impoundment sediment, and to verify these geophysical data with video photography and bottom sediment samples. The field program was a cooperative effort between the USGS Coastal and Marine Geology Team of the Geologic Division and the USGS Columbia River Research Laboratory of the Biological Resources Division. The data collection was completed aboard the R/V ESTERO during September 13-27, 2000. The interest in sediment accumulation in the reservoir was two-fold. First, it was unknown how effective this reservoir was as a sediment trap to material that otherwise would have been transported down-river to the estuary and eventually to the ocean. The recent erosion of beaches along the Washington coast has been attributed to a decreased contribution of sediment from the Columbia River to the coastal system due to the damming of the river. Second, sediment accumulation on the floors of reservoirs along the Columbia River has been suggested to be diminishing salmon spawning grounds. The extent of changes in habitat since construction of the John Day Dam, however, had not been documented. Common data sets were needed to address both of these questions, and for these reasons this geophysical and sampling program was undertaken.
The chirp seismic-reflection profiles were collected to measure the thickness and distribution of sediment that has accumulated in the John Day Reservoir since impoundment in 1968.

The navigation was collected with a P-Code plugger navigation system. Although the navigation antenna was mounted on the ship rather than the towfish, the system was towed shallow and extremely close to the boat therefore making the "layback" error negligible. Because of the high fire rates of the system, each "shot" does not have a navigation point, therefore these values have to be interpolated. Assumed accuracy 20 meters
The SIS-1000 system acquires chirp sidescan-sonar and chirp seismic-reflection data. Navigation is merged with these data. Since one system acquires both sets of data, only one trackline file is needed. In this case, the navigation extraced from the sidescan-sonar data was reformatted and converted to an Arc ungenerated format using awk scripts.

This ungenerate file (polyline format) was then imported into ArcView3.2 using an avenue script.

Additional attributes were added to the table of the shapefile to further describe each line of data, as well as allow hotlinking to seismic-reflection profile images.

Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Added year to the title. Added the link to the data catalog page in the Identification section, and a link to the publication in the Larger Work Citation. Added online link to the data in the Distribution section. Added a link to the field activity. The information in the quantitative horizontal accuracy assessment was moved to the horizontal positional accuracy report. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
